PDTC0
Control complementary PWM to delay a dead-time at every rising edge or falling
edge. Reset value = 0.
1 = Dead-time is inserted at falling edge.
0 = Dead-time is inserted at rising edge.
PDTC0.4 - controls the pair of (PWM0, PWM1).
PDTC0.5 - controls the pair of (PWM2, PWM3).
PDTC0.6 - controls the pair of (PWM4, PWM5).
PDTC0.7 - controls the pair of (PWM6, PWM7).
3-0
PDTC0
Enable dead-time insertion; Dead-time insertion is only active when the pair of
complementary PWM is enabled. Reset value=0. If dead-time insertion is
inactive, the outputs of pin pair are complementary without any delay.
1 = Programmable dead-time is inserted into the pair signals of comparator output
to delay the pair signals change from low to high.
0 = Disable dead-time insertion.
PDTC0.0 - enables the dead-time insertion on the pin pair (PWM0, PWM1).
PDTC0.1 - enables the dead-time insertion on the pin pair (PWM2, PWM3).
PDTC0.2 - enables the dead-time insertion on the pin pair (PWM4, PWM5).
PDTC0.3 - enables the dead-time insertion on the pin pair (PWM6, PWM7).
